== Description of the activity ==
Pellet injection is not only a widely used tool in magnetically confined plasma devices for core fuelling, but it is also expected to be a key part of the operation of future fusion reactors. Although the main physics of pellet ablation and of the subsequent particle deposition processes are fairly well understood, significant research is still needed to achieve a more complete knowledge of these processes. In particular, the drift of the ionized part of the pellet material, or plasmoid, is not fully comprehended. For instance, experimental observations deviate significantly from theoretical expectations in several stellarators <ref>J. Baldzuhn et al., Plasma Phys. Control. Fusion 61 (2019) 095012</ref> <ref>A. Matsuyama et al., Nucl. Fusion 52 (2012) 123017</ref>. Understanding the mechanisms responsible for these differences is highly important, since plasmoid drift determines the deposition of the pellet material and the efficiency of the fuelling.
Plasmoids and their drifts have been observed in TJ-II plasmas using a fast camera. However, the experimental conditions under which plasmoid drifting has been recorded to date are very limited. In order to increase our knowledge of plasmoid drift and its dependence of different parameters, a scan in magnetic configuration is proposed for both ECRH and NBI plasmas. The aim of these experiments is, on the one hand, to quantify plasmoid drift in the early stages of the homogenization process, and its relationship with quantities, such as plasma density and temperature or magnetic configuration (rational surfaces). On the other hand, it is intended to compare experimental results with HPI2 predictions, which will be part of the current effort to benchmark the stellarator version of HPI2 for TJ-II, W7-X, LHD and Heliotron-J devices.

UPDATE: after the first part of the campaign, goals are:
- Complete configuration scan in ECRH: 100_50_65
- Complete configuration scan in balance NBI: 100_50_65, 100_52_66 and 100_64_67
- New scan configuration in ECRH to study plasmoid drift for different magnetic well (for instance: 100_44_ 77, 099_44_99 and 100_43_104)

TJ-II: Spectroscopic studies of TESPEL-shell ablation clouds

== Description of the activity ==
Tracer-encapsulated solid pellets (TESPELs) are used to inject a known amount of tracer impurity particles inside the plasma at a well-localised radius. This is done with the aim of investigating impurity transport and accumulation in helical plasmas <ref>N. Tamura et al., Plasma Fusion Res. 10 (2015) 1402056</ref>. Over the past few years, quite an effort has been put into adapting the Hydrogen Pellet Injection 2 (HPI2) code <ref>B. Pegourié et al., Nuclear Fusion 47 (2007) 44</ref> for impurity pellets such as TESPEL (C8H8 shells). The ablation module of this code has already been successfully modified. However, simulation of the homogenisation processes for impurities is not straightforward. A first step in the calculation would be estimating plasmoid initial parameters, such as size, density, temperature, or ionization state, using the value of local ablation. Still, since obtaining the ionization state of the C is a significantly complicated task, some simplifications are mandatory. For instance, the problem could be considerably reduced if including in the model one or two ionization states were sufficient. Prior theoretical analysis (although solely for carbon pellets) point out to C II, C III and C IV states, at least in the early stage. However, C IV has not been detected so far as suitably intense emission lines need to be detected in machine sector close to the TESPEL injection port. To support such simplifications, further experimental input would be necessary <ref>M. Goto et al., J. Phys. B 43 (2010) 144023</ref>. With this in mind, TESPEL injection experiments using C8H8 shells only are proposed for TJ-II.
The idea is to inject ≤300 μm diameter TESPELs without tracers (C8H8 only) into ECRH plasmas. The evolution of the TESPEL shell ablation cloud would be followed with photodiodes and a fast camera to localize C ionization states during the early phase of the homogenization phase. Prior to that, emission lines of interest must be identified using a visible spectrometer that views the initial ablation process in order to identify interference filters for use with the fast camera. In the second phase, injections can be made to obtain fast-frame images of the ablation processes of interest. Reproducible plasmas with line-densities of the order <math>4.5 x 10^{18} m^{-3}</math> are needed. Injections can be made close to the end of discharges to avoid problems due to the increased plasma density that occurs after a TESPEL injection.

== Description of the activity ==
Pellet injection is a widely used tool in magnetically confined plasma devices for core fueling. Although the main physics of pellet ablation and of the subsequent particle deposition processes is fairly well understood, significant research is still needed to achieve a more complete knowledge. For instance, pellets are found to be accelerated, in the absence of suprathermal particles, in, at least, the vertical and radial directions in tokamaks and in some stellarators, such as W7-X <ref>J. Baldzuhn, Plasma Physics and Controlled Fusion (2019)</ref>. This acceleration is usually attributed to an asymmetry of its shielding cloud, however, the particular mechanism responsible for such an asymmetry remains outstanding <ref>T. Szepesi, Journal of Nuclear Materials (2009)</ref>.
In TJ-II ECRH plasmas, fast camera measurements show that pellet acceleration is negligible along most of the pellet trajectory <ref>N. Panadero, Nuclear Fusion (2018)</ref>. However, at the end of the pellet lifetime, a small variation of the pellet trajectory is sometimes observed. It should be possible to measure such deflection and to relate it to a non-negligible acceleration. For that, pellet injections, recorded with a double-bundle fast camera system, in TJ-II ECRH plasmas are proposed here. The aim of these experiments is, on the one hand, to quantify pellet acceleration and its relationship with quantities, such as plasma density and temperature or magnetic configuration. On the other hand, it is intended to compare experimental results with a recent extension of the acceleration model include in HPI2, that allows handling poloidal accelerations as well as radial ones. These studies are part of D. Medina Fusion-EP master thesis, as well as of current effort to benchmark the stellarator version of HPI2 for TJ-II, W7-X and Heliotron-J devices <ref>N. Panadero, 22nd ISHW (2019)</ref>.

TJ-II: Filter spectroscopy for pellet ablation cloud in TJ-II NBI plasmas

'''Filter spectroscopy for pellet ablation cloud in TJ-II NBI plasmas'''

== Name and affiliation of proponent ==
G. Motojima, National Institute for Fusion Science, Toki, Japan

== Details of contact person at LNF ==
Nerea Panadero, Ciemat

== Description of the activity ==

Here we propose filter spectroscopy measurements to measure the emission from the pellet ablation cloud in TJ-II. The electron density and temperature of the pellet ablation cloud are important to understand the ablation physics and to compare the simulation of the pellet ablation. The filter spectroscopy measurements contribute to the estimation of the cloud density and temperature assuming that ablation cloud is in local thermodynamic equilibrium (LTE).

In LHD, the filter spectroscopy shows that the cloud electron density is estimated to be from <math>1 × 10^{22}</math> to <math>3 × 10^{23} m^{−3}</math>. Also, the observed plasma cloud temperature, being about 1 eV, indicates the presence of a weakly ionized plasma cloud <ref>G. Motojima, Review Scientific Instruments (2012)</ref>. Recently, the similar measurements have been conducted in Heliotron J. Preliminary results suggest the similar density range of plasma cloud density. If the measurements will be conducted also in TJ-II, the pellet ablation cloud parameters could be compared with various stellarator/heliotron devices. This could contribute to the physics understanding of pellet ablation. Moreover, the results are probably important for the development of stellarator/heliotron concept.
